is a 2005 role-playing video game developed and published by Square Enix for mobile phones. Forming part of the Code Age media franchise, the story follows the character "Lost L" as they struggle to survive through an apocalypse brought upon the world by its control system as an imperfectly-created Warhead hybrid. Gameplay sees Lost L fighting other Warhead, absorbing them and using their powers in future combat, with the game featuring multiplayer combat with other players. The concept for Code Age was created in 2002 by Yusuke Naora, with the development team of Brawls using the project to expand upon the multiplayer communication of Before Crisis: Final Fantasy VII. Miwa Shoda wrote the scenario, while Kumi Tanioka composed the soundtrack. As with the rest of Code Age, Brawls remained exclusive to Japan. It released five story chapters between December 2005 and July 2006, before shutting down in September 2006. Journalists at the time it was demoed highly praised the demo's character models and graphical detail. Gameplay Code Age Brawls was a role-playing video game; players controlled the character Lost L, and the game was split between 2D pre-rendered environments navigated by the player character in 3D, and 3D battle environments. Battles are turn-based and consist of five rounds. Each player must select actions represented by colored badges, with each having strengths and weaknesses to others similar to a rock-paper-scissors mechanic. Once both players have made a selection, the badges are revealed, and the winner does damage to the opposing player based on the difference between their levels. The badge colors are ranked in power from highest to lowest as yellow, red, blue, purple, and gray. If players play the same color they both attack, and if one player's color is higher only they attack. Players may choose to not play a badge in order to save it for later rounds; if both players do not play a badge then neither attacks. After winning a battle, the player gains access to the opponent's form and abilities, equivalent to a character class with themed weapons and equipment, and variations depending on the lead's gender. A chosen form also influences how players can use their badges. In the original version, alongside single-player combat against computer-driven opponents, network-based multiplayer was incorporated to allow players to compete in one-on-one battles, linking up through matchmaking with nearby phones playing the game.
